The May 2026 Informative Bulletin No. 636, published on June 10, 2026, provides an overview of recent tax regulations and procedural updates from the Direction General of Revenue. It announces adjustments to the withholding tax rates for specific economic activities, introduces new electronic filing requirements for large taxpayers, and outlines the timeline for the upcoming quarterly advance tax payments. The bulletin also highlights the implementation of a revised anti‑avoidance rule targeting cross‑border transactions, specifying new documentation thresholds that taxpayers must submit to support transfer pricing analyses. Additionally, it presents guidance on the use of the updated digital platform for submitting tax returns, detailing step‑by‑step instructions for accessing the portal, uploading supporting files, and verifying receipt confirmations. The document includes reminders about the upcoming deadline for the annual income tax return filing, which is scheduled for early August, and offers extensions for certain categories of contributors. Finally, the bulletin disseminates information on newly available statistical reports regarding tax collection performance, encouraging taxpayers to consult these datasets for better forecasting and compliance planning. The bulletin also announces a series of virtual workshops scheduled for late June and early July, aimed at clarifying the new depreciation schedules and providing practical examples of asset classification under the revised tax code. Participants will receive detailed handouts and will be able to submit questions through an integrated Q&A session with DGI specialists. Moreover, it emphasizes the importance of updating taxpayer identifiers in the system before the end of the month to avoid processing delays for upcoming declarations. The publication concludes with contact information for the taxpayer support desk, including phone numbers and email addresses, encouraging stakeholders to reach out for personalized assistance.
